paul, dr. paul, good to see you. thanks for joining us. so you say if enough people use bit coin it could help bring down the dollar? you think that's a real possibility? am i getting what you said wrong? and maybe next time it won't be so successful. but the dollar has been under attack since the fed was created in 1913. it has lost 97% of its value. and the end stages of a paper currency always goes very quickly although it has been gradual for these hundred years, although there could come a day where i expect it will be panic for the dollar. >>> i want to get your thoughts on some of the big issues of the day. primarily let's talk about your son, senator rand paul of kentucky not hiding the fact that he is contemplating a presidential run, you've run three times, i'm sure you've given him much fatherly advice. but share a little bit with us if you would, what should he look at if he pulls the trigger, and do you think he should go for it? >> well, i think he is going to make up his own mind. and i had my opportunity to give him advice
